What is the electron configuration of an atom with the atomic number 3, and how does it relate to its position on the periodic table?
The electron configuration of an atom with the atomic number 3 (lithium) is 1s2 2s1. This means it has 3 electrons, with 2 in the first energy level and 1 in the second energy level. The position of lithium on the Periodic Table is in the second period and the first group (or column), which indicates its outermost electron is in the s orbital.
What else can I help you with?
What can you predict about an element by its position on the periodic table?
By the position of an element on the periodic table you can tell how many protons the element has in it by looking at the number above the elements symbol. You can also find the electron configuration with that same number then you can and you can you can also tell if it is f1, f2,f3...s1,s2,d1,d2...
What can you predict about an element from its position in the period table?
An element's position on the periodic table can give insight into its properties such as atomic number, atomic mass, electron configuration, and reactivity. Elements in the same group have similar chemical properties due to their electron configuration, while elements in the same period have the same number of electron shells.
How does electronic configuration of an atom relate to its position in the modern periodic table?
The electronic configuration of an atom is related to its position in the periodic table because elements in the same group have similar electronic configurations due to having the same number of valence electrons. Elements in the same period have varying electron configurations as atomic number increases across the period. This organization helps predict elements' chemical properties and behaviors.
Which element is represented by the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2?
Calcium. To get the answer easily, count up the electrons, then look for that atomic number on the periodic table

An elements properties can be predicted from its?
An element's properties can be predicted from its position on the periodic table, specifically its atomic number and electron configuration. These characteristics influence an element's chemical and physical properties, such as reactivity, conductivity, and melting point.
What can you predict about an element from its position in the period table?
An element's position on the periodic table can give insight into its properties such as atomic number, atomic mass, electron configuration, and reactivity. Elements in the same group have similar chemical properties due to their electron configuration, while elements in the same period have the same number of electron shells.
Does Ca2 have an identical electron configuration as anything else?
No, calcium (Ca) has a unique electron configuration due to its atomic number and position in the periodic table. Its electron arrangement is 1s2 2s2 2p6 3s2 3p6 4s2. While there are other elements with similar electron configurations, none are identical to calcium.
What is the electron configuration?
The electron configuration is a representation of how electrons are distributed among the various atomic orbitals in an atom. It is often written using the notation of the periodic table, indicating the number of electrons in each energy level or subshell.
What is the full electron configuration of barium?
The full electron configuration of barium (Ba), which has an atomic number of 56, is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s². This configuration indicates that barium has two electrons in its outermost shell, corresponding to its position in group 2 of the periodic table as an alkaline earth metal.

About the electron configuration?
Electron configuration for an atom is the distribution of electrons on atomic orbitals.
What is the electron configuration of atomic number 26?

What is the energy level for atomic weight 11?
Atomic weight 11 corresponds to the element sodium (Na), which has an atomic number of 11. In terms of energy levels, sodium has three main electron shells: the first shell can hold up to 2 electrons, the second can hold 8, and the third shell has 1 electron. This configuration reflects its position in the periodic table and contributes to its chemical properties, particularly its reactivity and tendency to lose that single outer electron to achieve a stable electron configuration.
